London-based designer David Quay designed ITC Quay Sans in 1990. One of the precursors to the long run of functionalist European sans serif faces that has been a dominating force in type design since the 1990s, ITC Quay sans is based on the proportions of 19th Century Grotesk faces. Grotesk, the German word for sans serif, defines an entire branch of the sans serif movement, which culminated in the 1950s with the design of Helvetica. ITC Quay Sans is made up of very simple, legible letters. The weights of the strokes throughout the alphabet vary very little. Microscopic flares on the ends of each terminal add a bit of dimension to the design. This helps prevent the onset of the monotony, a danger when one repeats countless near mono-weight stroked letters throughout a large body of text. ITC Quay Sans is a very readable face; it works equally well in all sizes. Six fonts of the ITC Quay Sans typeface are available: Book, Book Italic, Medium, Medium Italic, Black, and Black Italic. ITC Quay Sans is similar to Hans Eduard Meier's Syntax, and Tim Ahrens' Linotype Aroma.
